Job details:
About the RoleAt Evoxia, we are reshaping the environmental footprint and supply chain security of the solar sector. We bypass carbon-heavy legacy smelting to manufacture ultra-high-purity solar silicon using biogenic feedstocks and clean plasma reduction.
We are looking for a highly specialized Experimental Plasma Physicist to own the physical deployment, configuration, and optimization of our high-temperature thermal plasma systems. This role requires a hands-on builder who moves seamlessly from first-principles plasma physics to physical hardware execution, component specification, and reactor troubleshooting under extreme hydrogen atmospheres.
What You Will Do:- Equipment Specification & Selection: Lead the technical definition and component sourcing for our complete plasma subsystem—including DC/RF power supplies, thermal plasma torches, mass flow controllers, gas-mixing manifolds, and vacuum interfaces.
- System Integration & Configuration: Design, assemble, and configure the physical interfaces between power sources, working gas lines, and the high-temperature reaction chamber to optimize energy transfer efficiency.
- Hydrogen Ratio Optimization: Own the experimental roadmap to safely scale plasma gas compositions to high-concentration and pure hydrogen processing atmospheres, managing the severe thermal loads and voltage shifts associated with molecular gas dissociation.
- Diagnostics & Troubleshooting: Deploy and interpret real-time process diagnostics (e.g., Optical Emission Spectroscopy (OES), enthalpy probes, and thermal imaging) to systematically resolve arc instabilities, jet fluctuations, and premature electrode degradation.
- Safety Engineering: Implement fail-safe gas handling controls, nitrogen-purging loops, and automated isolation valves for high-volume hydrogen operations.
What We Are Looking For:- Education: Ph.D. in Plasma Physics with a dedicated, verifiable track record of hands-on experimental research or industrial operations.
- Experimental Expertise: Extensive laboratory experience directly building, modifying, operating, and troubleshooting physical thermal plasma systems and reactors.
- Hardware Competency: Deep practical understanding of torch cathode/anode erosion mechanics, arc-root behaviors, and matching power supply impedance to dynamic plasma loads.
- Hydrogen Gas Handling: Direct experience managing high-temperature reducing or flammable gases, with an acute understanding of how hydrogen's high thermal conductivity alters arc voltage characteristics.
Why Join Evoxia?- Complete System Ownership: You will spec, configure, and optimize the core plasma architecture of our scaling pilot from the ground up.
- Institutional Momentum: Work with an agile team backed by premier deep-tech and clean-tech validation.
- Hardcore Climate Impact: Your physical engineering outputs directly translate to removing megatons of industrial CO2 and building clean energy sovereignty.
